Four typical forest types in Sygera Mountain, namely, Pinus armandii (PA), Picea likiangensis var. linzhiensis (PLL), Abies georgei var. smithii (AGS), and Juniperus saltuaria (JS) were considered using methods such as analysis of variance and stoichiometry. Effects of changes of nutrient content and stoichiometric ratio of various organs of arbor plants were evaluated. Compared with global plant nutrients, this study area had lower N and P contents. The growth of the Juniperus saltuaria forest was jointly restricted by N and P, and as the environmental gradient decreased, the growth of the ot...
